In the wiki article is explained, that the Xorg Intel TearFree option has the following disadvantages:

''"However, the way this option acts makes it redundant with the use of a compositor (it increases memory consumption and lowers performance, ..."''

As far as I understand this is not true anymore.

as the command to start a {{ic|gnome-session}}. But {{ic|dbus-run-session}} starts a new dbus session and this somehow prevents for example evolution to access my default keyring. I dont know why, but simply starting {{ic|gnome-session}} works. I dont know with which dbus instance the gnome-keyring starts through its .desktop files in {{ic|/etc/xdg}} but the problem seems to be that these 2 would run on different instances of dbus.

::'''''Note that this replicates what the compositing manager should be doing, however TearFree will redirect the compositor updates (and those of fullscreen games) directly on to the scanout thus incurring no additional overhead in the composited case.'''''

I do not want to edit the wiki page as long as i dont know if this is my mistake or really a mistake on the page. I will look into this in the next week, until then, any guidance is appreciated.

::'''''Thus enabling TearFree requires more memory and is slower (reduced throughput) and introduces a small amount of output latency, but it should not impact input latency.'''''

::My assumption from reading this is that TearFree will lower performance but that using a compositor won't make things worse. We could delete the following words from the sentence in question: ''"makes it redundant with the use of a compositor (it"''

I believe this is not just about GNOME, but all GTK+ and Qt applications [1][2]. Haven't read through the reports, but it appears to be some flaw in Xorg. Not much we can do about this, so unless you want to discuss a workaround this can be closed. -- Alad (talk) 19:50, 8 December 2014 (UTC)

Can you confirm this with another toolkit than GTK3 ? -- Alad (talk) 17:35, 10 January 2015 (UTC)

GNOME and fontconfig settings

Since there isn't a section dedicated to fonts in GNOME 3 I was thinking about writing one, but I put it here first:

GNOME doesn't use the dpi settings set by xorg server to scale fonts, instead it uses a fixed dpi of 96 that cannot be changed unlike previous versions:

The gnome-settings-daemon plugin xsettings relies on this hardcoded value for some calculations and there is currently no way of changing it beside customizing the code in abs. The dimension of text can be tweaked changing the text-scaling-factor (1.0 by default), using gnome-tweak-tool or editing the following key in dconf-editor:

org.gnome.desktop.interface.text-scaling-factor

The xsettings plugins will also merge some Xft values in the X resources db overwriting values set in .Xresources od .Xdefaults files. The defaults are:

Some of those values can be changed using dconf-editor (org.gnome.settings-daemon.plugins.xsettings) or gnome-tweak-tool. It is possible to change this values using xrdb -merge ~/.Xresources after gnome is started but gnome will still use its values internally so it is not a good idea.

It is a good idea to configure your fonts.conf in a way consistent with the gnome settings otherwise, at least on my laptop, fonts will looks weird in some gnome apps.

The dpi setting of the Xserver can be changed to 96 following this guide, this way it will be the same for all applications, the drawback is that fonts might look too small or too big in other application if the real DPI of your monitor differs too much from 96.

For and LCD monitor it is a good idea to activate the lcd filter setting the following keys in dconf-editor:

Since the lcdfilter is not designed to work together with autohinting it is a good idea to disable it also in fonts.conf.
It is also a good idea to use the same hinting value as in your font.conf, the default in gnome is medium:

Well, it is very GNOME specific and complex at the same time. I would vote for putting it into GNOME tips and crosslink it from GNOME#Fonts as well as from Font configuration. But first: Above contribution of Erm67 is a couple of years back. Does someone know whether the instructions still work like that? --Indigo (talk) 09:04, 10 November 2014 (UTC)

Update to note: GNOME tips was cleaned up removing GNOME content after I suggested above. It does not make sense to put these instructions there anymore. --Indigo (talk) 12:41, 15 January 2015 (UTC)

Manually start a Wayland session

as the command to start a gnome-session. But dbus-run-session starts a new dbus session and this somehow prevents for example evolution to access my default keyring. I dont know why, but simply starting gnome-session works. I dont know with which dbus instance the gnome-keyring starts through its .desktop files in /etc/xdg but the problem seems to be that these 2 would run on different instances of dbus.
